This adds a test for having multiple BlockBackends in one BDS tree. In
this case, there is one BB for the protocol BDS and one BB for the
format BDS in a simple two-BDS tree (with the protocol BDS and BB added
first).
When bdrv_close_all() is executed, no cached data from any BDS should be
lost; the protocol BDS may not be closed until the format BDS is closed.
Otherwise, metadata updates may be lost.

Remove "growable" option from the "open" command and from the qemu-io

will make sure that no request exceeds the image size, so the only way
to keep "growable" would be to use BlockBackend if it is not given and
to directly access the BDS if it is.
qemu-io is a debugging tool, therefore removing a rarely used option
will have only a very small impact, if any. There was only one

This case utilizes qemu-io command "aio_{read,write} -q" to verify the
effectiveness of IO throttling options.
It's implemented by driving the vm timer from qtest protocol, so the
throttling timers are signaled with determinied time duration. Then we
verify the completed IO requests are within 10% error of bps and iops
limits.
"null" protocol is used as the disk backend so that no actual disk IO is
performed on host, this will make the blockstats much more
deterministic. Both "null-aio" and "null-co" are covered, which is also

Add a test for the additional information now provided by qemu-img info
when used on qcow2 images. It also tests the qemu QMP output from the
query-block command when running qemu with different runtime options
than specified in the image (ImageInfoSpecific should always refer to
the image).

Add a -n option to skip volume creation on qemu-img convert.
This is useful for targets such as rbd / ceph, where the
target volume may already exist; we cannot always rely on
qemu-img convert to create the image, as dependent on the
output format, there may be parameters which are not possible
to specify through the qemu-img convert command line.

This test creates an image with unallocated zero clusters, then creates
a snapshot. Afterwards, there should be neither any errors nor leaks.

We don't want to commit to the API yet before everything is worked out.
Like already for 1.5, disable it again for the 1.6 release. This commit
is meant to be reverted after the 1.6 release.
The disabling of the driver-specific options is achieved by applying the
old checks while parsing the command line.

This patch adds tests for sync modes top and none. Test for 'TOP'
is separated out as it requires a backing file. Also added a test
for invalid format.

Test that qemu-img convert -c works when input image length is not a
multiple of the cluster size.
Previously an error message would be produced:
qemu-img: error while compressing sector 0: Input/output error
Now that qcow2 and qcow handle this case the test passes successfully.
